sql关联表的脚本：customers\u addresses
创建表customers\u addresses（idcustomer int not null，idaddress int not null，主键（idcustomer，idaddress），键fk\u cust（idcustomer），键fk\u add（idaddress），约束fk\u cust foreign key（idcustomer）references customers（idcustomer），约束fk\u add foreign key（idaddress）references address（idaddress）
